Videos
n Basal Trunk Spray Using Safari -- instructional video produced by Valent Corporation. This short video demonstrates how to do basal trunk spray with Safari 20 SG. Although it features ash trees instead of hemlocks, the technique is the same. One can see that it's rather easy to do, using a low-flow setting and being careful to apply it from about 5 feet high on the trunk to about 6 inches above the ground. (Wish it had shown the user wearing goggles and a mask -- always a good idea when working with chemicals!) 2010
